Don't want to be an idiot, but what about mute? Maybe it's just me, but I was going crazy over a problem that turned out to be a balance knob turned sideways. Also do you have an A B speaker switch? could be that they're both depressed, or the wrong one is pressed. Was is it working when it happened? was there a pop? Check the fuse. Replace with correct fuse. Good luck

I have marantz Av surround receiver model SR301 I have tried a lot but I am having sound from only 2 speaker when I put in setero mode but when I put in surround no sound from any speakers I checked all...


First off you will need to do a little bit of trouble shooting. Is the source (dvd, Blu-ray, cable box, etc...) plugged into the receiver with the standard red and white RCA cord or by an optical (toslink-fiber optic) or digital RCA (orange color code). If you are connected with a standard RCA cord then that it your problem and you need buy digital cord that both the source device and the receiver can accept (toslink - http://www.we-supply.com/browse.cfm/optical:-audio/2,779.html or Digital RCA). If the connection is now correct then you need to make your receiver do a "test-tone" to insure that a signal can be sent to every speaker (this is an internal test that just checks the speaker connections). If the tone tone operates correctly then you know the amplifier is functioning. If both of the mentioned things are now done and still not surround output then you need to check the internal menus on your source device and make sure that it does not require you to manual change a setting in the audio menu to make it work (i.e. change from 2-ch 44KHz to 5.1 or 7.1 or Dolby Digital or AC3 or some other surround sound protocol.)

My Sanyo DP23845 23 In. LCD Television does not have any options under set up beside color-how do I add channels?


HDTV inherently provides a superior sound quality simply because the sound of HDTV is digitally transmitted. The difference in sound between an HDTV television and an analog television is rather noticeable. In fact, it is directly analogous to the difference between the music on CD's compared to the music on audiocassette tapes.

The difference in sound quality provided by HDTV televisions and programming does not end there. Many HDTV programs are also broadcast in Dolby Digital 5.1 surround sound, but in order to take full advantage of this technology, it is necessary to have the right equipment.

Dolby technology has been created by Dolby Laboratories, Inc. This technology is the most renowned provider of digital audio technology. Also, Dolby Laboratories is known for reliable and superior products. For these reasons, Dolby Digital Surround has become the standard for HDTV. Many television manufacturers substitute their own surround sound systems, but they cannot live up to the reputation and performance of Dolby. Therefore, it important to check the specs on an HDTV television before buying in order to ensure that it uses Dolby Digital Surround.

When using Dolby Digital Surround Sound, there are three options for set up. The first option is to buy a television with high quality center channel speakers, woofers, tweeters, and Dolby technology installed in the television. With this option, it is unnecessary to buy addition equipment to take advantage of Dolby Digital Surround Sound.

Another option for taking advantage of the Dolby Digital Surround Sound with an HDTV is to connect an external set of surround speakers to the television. With this option, the surround sound set up includes a front pair of speakers, a surround pair of speakers, a center channel, and a subwoofer. Sometimes, the front speakers are "powered towers." This means these towers include subwoofers.

The placement of these speakers is very important for the quality of the surround sound. The Center Channel Speaker should be centered either above or below the television. The Front Left and Right Speakers should be placed in an arc formation in line with the Center Channel Speaker. The Surround Left and Right Speakers, on the other hand, should be placed to the left and right sides behind the listening position. Many people choose to wall mount these speakers.

The third option for taking advantage of the Dolby Digital Surround System included in an HDTV television is to use an external set of front speakers can be connected to the HDTV television. This configuration is useful if there is not enough room to set up the external surround sound system and the HDTV does not come with Dolby Digital Surround installed. This isn't true surround sound, but it is a viable alternative to those who can't take advantage of the first two formats.

The audio and video outputs of the DVD or VCR can be connected to the AV receiver's video outputs. If a separate DVD and VCR need to be connected, one can be connected to the VCR1 connection and the other can be connected to the VCR2 connection. The AV receiver's VCR video and audio outputs should then be connected to the audio and video inputs of the DVD and/or VCR. In this way, the DVD and/or VCR will be able to record video signals that come through the AV receiver and the VHS tapes and/or DVD's will be able to be viewed on the HDTV.

To take full advantage of the Dolby Digital Surround Sound technology, one of the video outputs of the DVD player and/or VCR needs to be connected to the AV receiver. The digital coaxial audio or digital optical connection must also be connected to the AV receiver.

How do I connect my CD player?

A CD player can be connected to an AV receiver. The CD player's digital audio outputs can be used to connect the CD player to the AV receiver. A CD-Recorder can also be connected the AV receiver by using the Audio Tape Record/Playback input/output loop connections. In this way, the CD-Recorder will be able to function much like a standard audiocassette deck.

What else will I need?

Besides the basic electronic equipment needed to set up Dolby Digital Surround Sound, it is necessary to have connection cables. This includes video, audio, and loudspeaker connection cables. These cables need to be at an appropriate length in order to set the speakers in the proper position for optimal surround sound quality.

All 5 speakers work on test mode but on surround sound the left and right rear speakers are not working. How can this be?


Hello Ruby,

This is because your receiver is not in the correct surround sound mode for the number of channels being sent from the audio source, i.e. your TV or DVD player. It is likely your receiver is set for Dolby Digital (DD). You will need to switch your receiver to a Dolby Pro Logic (PL or PL II) setting to get audio from the rear speakers using your current audio source.

If you are unsure how to do this, please reply to me with the brand and model of the receiver. Some receivers have a "Surround Mode" button on the front of the unit or the remote. If you want to include further details of your setup, I can also give you some advice on attaining the best audio quality with the equipment you are using. You may be able to get Dolby Digital surround by changing some audio settings on the audio source or using a different connection.

Hope this helps. Please let me know if you need further assistance.

Regards,
BElectric

I'm going to surround sound mode, and my rear speakers are not working. I do a tone test, and they def work, but I can't get them working right?


Since you seem to be having problems with 'simulated' surround, how does ACTUAL surround material behave?

Have you tried AFD with certifiable multichannel source material to verify the surround speakers receive programmed sound??

Do the Dolby Digital or Pro Logic indicators light?

What about the other modes?

Right now my reciever will only play with two speakers (L and R). How do I get the 5.1 DTS back?


Are you using single digital coaxial or optical digital or the stereo RCA cable.
You might have that buttons on the remote for surround,2channel,3channel or 5.1 channel. orGo to the DVD's setup menu and click on "Audio Setup" or on "Languages" if there is no Audio Setup option and choose "Dolby Digital 5.1." (If you have a5.1, 6.1 or 7.1 system select "Dolby Digital EX" if it is an available option.) Depending on the age of the disc, the "Audio Setup" on the DVD menu may give you several choices: "5.1 Channel Surround Sound" or "Stereo Playback." If it's an old DVD, it might even say Dolby AC-3 (the professional designation for Dolby Digital 5.1). New DVDs may offer "Dolby Digital 5.1" and "Dolby Digital 2.0," the latter being stereo. Some of the disc menus offer only "Surround Sound" or "Stereo" options.

Dolby digital


Dolby Digital includes several similar technologies, which include Dolby Digital, Dolby Digital EX, Dolby Digital Live, Dolby Digital Surround EX, Dolby Digital Plus, and Dolby TrueHD.

Dolby Digital, or AC-3, is the common version containing up to six discrete channels of sound. The most elaborate mode in common usage involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right front, center, left front, right rear and left rear) and one channel (20 Hz – 120 Hz allotted audio) for the subwoofer driven low-frequency effects. Mono and stereo modes are also supported. AC-3 supports audio sample-rates up to 48 kHz. Batman Returns was the first film to use Dolby Digital technology when it premiered in theaters in Summer 1992. The Laserdisc version of Clear and Present Danger featured the first Home theater Dolby Digital mix in 1995.

This codec has several aliases, which are different names for the same codec:

* Dolby Digital (promotional name, not accepted by the ATSC)
* DD (an abbreviation of above, often combined with channel count: DD 5.1)
* Dolby Surround AC-3 Digital (second promotional name, as seen on early film releases and on home audio equipment until about 1995/1996)
* Dolby Stereo Digital (first promotional name, as seen on early releases, also seen on True Lies LaserDisc)
* Dolby SR-Digital (when the recording incorporates a Dolby SR-format recording for compatibility)
* SR-D (an abbreviation of above)
* Audio Coding 3 (relates to the bitstream format of Dolby Digital)
* AC-3 (an abbreviation of above)
* Audio Codec 3, Advanced Codec 3, Acoustic Coder 3 (These are backronyms. However, Adaptive Transform Acoustic Coding 3, or ATRAC3, is a separate format developed by Sony)
* ATSC A/52 (name of the standard, current version is A/52 Rev. B)

Did it ever work properly? If not, let's get down to basics and set it up for the simplest configuration it can have: FM source in stereo with front left and right speakers, no Surround Mode, no DSP, no Tape Monitor, no Mute, Volume not turned all the way down. Does that work?

Do you have Surround Speakers defined in System Setup A? If not, only Dolby Surround or Off are valid Surround Modes.

Is T2 Monitor indicator lit? Press the Tape-2 Monitor.
Is there acceptable sound other than during Speaker testing? NO? Is MUTE On?
